Data from the James Webb Space Telescope indicate that a galaxy known as GN-z11 has a supermassive black hole at its center — one that's far more massive than astronomers expected.
On Earth, clouds and rain are made of water. But the James Webb Space Telescope has found that on a planet called WASP-107b, the rain and clouds are made of sand.
A new image from NASA's James Webb Space Telescope reveals what Earth's sun could have looked like in its infancy.
A stunning new image from the James Webb Space Telescope shows a pair of actively forming stars. But many people are more curious about the tiny question mark visible toward the bottom of the frame.
Thanks to the James Webb telescope, we can now see the nebula with more clarity. As one expert says, "We always knew planetary nebulae were pretty. What we see now is spectacular."
Astronomers pointed the James Webb Space Telescope at a common kind of planet that's bigger than Earth but smaller than Neptune. What they saw wasn't what they expected.
At about 600 million years after the Big Bang, they're not the oldest galaxies the telescope has spotted. But they appear as developed as our Milky Way — far further along than researchers expected.
Astronomers are debating how quickly the observations of the Hubble Space Telescope and the James Webb Space Telescope should be made public.
One year ago, on Christmas Day, the James Webb Space Telescope was launched. Since it began collecting data, it has captured - in stunning detail - previously unobservable stars, planets and galaxies.
NASA says an extensive review of historical records found no evidence that Webb ever led or supported purges of government employees who were gay. But some astronomers think that's a pretty low bar.
Galaxies that existed soon after the Big Bang turn out to be surprisingly bright, a discovery that's both thrilled and puzzled scientists who study how the universe evolved over time.
The James Webb Space Telescope has captured NASA's most detailed image of the Pillars of Creation that is helping scientists better understand how stars form.
The last time scientists caught such a clear glimpse of Neptune's rings was when Voyager 2 flew past the distant planet in 1989. Now the James Webb Space Telescope has delivered a crisp new image.
The telescope uses a camera with filters that can make a color map out of infrared light, which is invisible to the human eye.
Bill Ochs, the project manager for the James Webb telescope shares the trials and tribulations of the launch and what it's like having the images out in the world.
